The effect of finite container size on granular jet formation
Stefan von Kann, Sylvain Joubaud, Gabriel A. Caballero-Robledo +2
When an object is dropped into a bed of fine, loosely packed sand, a surprisingly energetic jet shoots out of the bed. In this work we study the effect that boundaries have on the…
Collapse of Non-Axisymmetric Cavities
Oscar R. Enriquez, Ivo R. Peters, Stephan Gekle +4
A round disk with a harmonic disturbance impacts on a water surface and creates a non-axisymmetric cavity which collapses under the influence of hydrostatic pressure. We use disks…
Supersonic Air Flow due to Solid-Liquid Impact
Stephan Gekle, Ivo Peters, Jose Manuel Gordillo +2
A solid object impacting on liquid creates a liquid jet due to the collapse of the impact cavity. Using visualization experiments with smoke particles and multiscale simulations we…
